The final product is absolutely gorgeous. Everything turned out better than we even pictured. Most of all I appreciated the open ended communication. They talked to us all the time and called to make sure we were happy. They also called to update us and to ask if we felt like anything needed to be changed. That was wonderful.

At first, I interviewed Renewal by Andersen and had an awful experience with high pressured sales and at the end of the day an inferior product for more money. That's when I called Global and Infinity by Marvin. They are an exceptionally wonderful company and I have no problems recommending them to anyone. I speak highly of the company and its skilled laborers . Everyone involved from the ground up is worth every penny spent!!!
